Wadi al-Hitan: Discovering the Extraordinary Valley of the Whales
Southwest of Cairo, in the heart of the Egyptian Western Desert, lie treasures even older than the tombs of the pharaohs. They offer those who come to see them a new perspective on the great mysteries of evolution. A multitude of figures bring the story of ancient Egypt to life, from Tutankhamun and his golden funerary mask to the enigmatic Sphinx of Giza. But those who travel 160 kilometres south from Cairo and venture into the sandy expanses of the Western Desert will have the opportunity to go back even further in time and immerse themselves in an era when Egypt was populated not by kings but by monsters. There, at the end of a long track, lies Wadi al-Hitan, a 195-square-kilometre UNESCO World Heritage Site that is said to hold the key to one of the greatest mysteries of evolution.
Wadi al-Hitan: A Silent Landscape Frozen in Time
Yet, it’s hard to believe at first glance. Life is absent from this sandy valley: no houses, no trees, no water; only miles and miles of desert stretching in every direction, as endless and golden as all the riches of the pharaohs. A profound silence here compensates for the clamour of Cairo. Although tourists flock to see the treasures of the Valley of the Kings, Wadi al-Hitan remains a largely overlooked gem. Yet, this remote place tells a powerful story about life on Earth, buried by the sands of time, quite literally, and now brought back to the surface by wind erosion and the meticulous work of palaeontologists.
Wadi al-Hitan: Walking Through a Prehistoric Graveyard
Fossil enthusiasts visit the Valley of the Whales on day trips from Cairo. In the heart of the desert, they discover rocks sculpted by millennia into otherworldly forms. Bulbous kiosks, compact rotundas, and giant mushrooms dot a landscape battered by relentless winds. A sandy path winds through them, recognizable by the carefully placed stones along its edges and the overlapping footprints of visitors. This is one of the most barren environments on Earth, and yet, groups of curious visitors who ascend this path, which crunches gently underfoot and winds its way between the rock formations, discover the vestiges of prehistoric life: smooth mollusk shells catch the light; there are coin-shaped fossils of marine animals called nummulites; and even shark teeth.
Wadi al-Hitan: From the Tethys Ocean to the Desert Floor
These are things you wouldn’t expect to find in a desert located 160 kilometres from the coast. But 40 million years ago, the continents looked very different, and what is now a shallow ocean, the Tethys, entirely submerged North Africa. But there are other, even more telling, vestiges of this enigmatic past: bone fragments scattered like puzzle pieces, vertebrae the size of concrete blocks. Even more spectacular and surprising is the remarkably well-preserved skeleton of an enormous predator lying on the sand at the end of the track. Its spine is the size of a cricket pitch, and its ribs lie on either side of it like stakes knocked over by a spin bowler.
Wadi al-Hitan: Unmasking the Lizard King
“When scientists discovered this creature, they thought it was a giant marine reptile,” reveals Hesham Sallam, senior palaeontologist at Wadi al-Hitan. “So they named it Basilosaurus, which means ‘lizard king.’ It was only later that they realized it was a whale.” For over a century, palaeontologists have been unearthing prehistoric whales here. Around 1,000 specimens have been identified, making this the largest whale graveyard on Earth and one of the most important paleontological sites. It is for this reason, and regarding the Valley of the Kings, Egypt’s most famous necropolis, that they named the place Wadi al-Hitan, the Valley of the Whales.
Wadi al-Hitan: Seeing Evolution with the Naked Eye
In the sands of the wadi, a dozen whales can be admired, all belonging to the genera Basilosaurus and Dorudon. Their dating reveals that they lived 37 to 40 million years ago, during the Late Eocene. Arranged in a way reminiscent of open-air exhibitions, the whale remains are connected by pathways that allow visitors to discover them one by one. One feels a certain fascination scrutinising these bones, which also prove crucial for understanding some of the most bizarre stories of evolution, the key to which lies in the site’s small underground museum.
Wadi al-Hitan: The Mystery of the Vestigial Legs
There, alongside a pair of meter-long Basilosaurus skulls with terrifying teeth, lies the monster’s most astonishing (and strangely comical) attribute: a pair of tiny hind legs complete with femurs, tibias, and ankles, also equipped with matchstick-like feet. “When you think about it, it’s strange that whales are air-breathing mammals yet live in the ocean,” observes Hesham Sallam. “Scientists have theorized that they must have first appeared on land before going into the water and evolving into the giants we know today, losing their legs in the process.” But for decades, they had no proof of this.
Wadi al-Hitan: The Crucial Evolutionary Link
These leg bones, discovered in 1989, provide a crucial link in this transformation. They are slender, no bigger than a human arm, and thus, attached to this six-ton whale, they couldn’t have been used for walking. But they provide clear evidence that the ancestors of whales evolved on land and that whales later abandoned their terrestrial lifestyle for the water. “It’s like being able to see evolution with the naked eye and touch it,” he explains. “You have to be careful where you step, because there are fossils everywhere, and you never know what discovery might be lying beneath your feet.”
